SAMUEL BEATTY, OF NORWALK, CONNECTICUT.

IMPROVEMENT IIN PERFORATED WIRE.

Specification forming part of Letters Patent No. 102,358, dated April 26, 1870.

To all whom it may concern:

Be it known that I, SAMUEL BEA'r'rY, of Norwalk, in the county of Faireld and State of Connecticut, have invented a Perforated Wire, of which the following is a specification, reference being had to the accompanying drawings. v

My invention consists in producing a new article of manufacture, the same consisting of a flattened perforated wire, as hereinafter more fully explained.

In the accompanying` drawings, Figures l and 2 represent the Wire in its various stages of preparation. Figs. 3 and 4 represent the same completed, ready for use.

In constructing my improved article, I first take around wire, a, of the proper size an d pass it between rolls, thus attening it, as represented by b of Fig. l. lt is again rolled and iiattened out still more, and so on continuously until it is reduced to the requisite thinness, each rolling reducing its thickness and increasing its width, as represented by the various cross-sections shown in Fig. l. As these successive rollings 'have a tendency to harden the metal and render it rigid and brittle, it is sometimes necessary to anneal or soften the same, this necessity depending upon the quality of the wire, the number of times it is subjected to the action ofthe rolls, and the purpose for whichit is to be used, some purposes requiring that it should be left as stiff as possible, and others requiring that it should be soft and pliable. At'ter havin g thus rolled the wire out into a thin, iiat strip, as represented in Fig. 2, where it is shown much enlarged, and in which condition it resembles the ordinary hoop-skirt wire, lI, then perforate it with a series of holes, as shown in Fig. 3, also enlarged. This may be done by any of several well-known mechanical means-as, for instance, by a punch, press, or by rolls provided with suitable punches and recesses or dies. These perforations may be made in any suitable style or order, according to the purpose for which the wire is to be used, they being formed in a single row or series along the center, as shown, or in pairs or rows near the opposite edges, these holes being directly opposite each other, or placed alternately in zigzag form or order, as may be preferred. y In preparing thewire for use in forming hatventilators, for which it is admirably adapted, I prefer to form the perforations in a single row along the center, and of an elongated forin, as represented in Fig. 3, and at e of Fig. 4, this arrangement and form of the perforations rendering the material less lia-ble to injury by fracture or breaking in punching the holes, and also permitting it to be more readily corrugated without injury. The perforations may be varied in form, they being made as shown, or rounded or oval, as preferred. When intended for hoop skirts, bon net-frames, and similar purposes, the perforations may be formed only at intervals, as represented at f, Fig. 4, the perforations in such case being intended for stitching it fast with a needle and thread, or for permitting the metal fastening, it' such be used, to pass through the perforation, and thus prevent the wire from slipping. It will be observed that a flat metal ribbon formed by rolling down'a round drawn wire will have smooth and rounded edges, as represented in Figs. l and 2, and that such a Wire may be much more readily covered with thread or fibrous covering of any kiiidgvithoutdanger of inj uriug the saine, than could be a strip of metal cut from a sheet, as the latter would have a rough edge, and tend to tear or cut the covering. v

My perforated wire may be made of any re- 'quired size, with or wit-hout being tempered, as desired, and may be covered or used without, as required.

By this method of preparing the wire I produce a now article of manufacture that is adapted to many purposes.

Having thus described my invention, what I cla-im is- The herein-described iiattened and perforated wire, as a new article of manufacture.

SAMUEL BEATTY.
